To all whom t may concern.'

Be .it known that I, HARRY O. BREAKER, a citizenof the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvement-s in Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the. art to which it appertains to make and use the same. I The invention relates to water heaters, and more particularly to a heater adapted to .utilize the waste heat in the exhaust 15 gases from internal combustion engines.

The object of the invention is to provide a water heater of this character which is well adapted to resist the action of the acids and other compounds usually contained within the exhaust gases from gas and other internal combustion engines, and to also provide a heater the parts of which may be readily and conveniently manufactured and assembled, and may be readily repaired without requiring the dismantling of 'the` heater.

To this end the invention consists in the features of construction and combination of parts hereinafter described and set forth in the claims.

rlhe various features of the invention will be readily understood from an inspection of the accompanying drawings and thc following detailed description of the heater In the drawings Figure 1 is an elevation partlyv in section of a heater embodying the invention, the section bein taken on line 1-1, Fig. 3; Fig. 2 is a p an view with a part of the inlet chamber broken away; and Fig. 3 is a horizontal section on line 3 3, Fig. 1.

The heater shown in the drawings comfprises generally inlet and outlet chambers connected by pipes through which the exhaust gases pass, and a casing surrounding the pipes to form a water chamber through which the water to be heated flows, and by which it is brought' in to contact with the pipes. The heater is-formed in sections so constructed that they may be readily manufactured and assembled, and so connected together that convenient access may be had to any parts irequiring inspection or repair Specification of Letters `Patent.

without the necessity of dismantling theN/ heater. The inlet, outlet, and pipe sections are formed of cast iron, and are so constructed and arranged that only cast iron surfaces wh-ich will effectively resist' the action of the acids and other corrosive compounds therein are subjected to the action of the gases.

. AS shown in the drawings the pipe section comprises a series of cast iron pipes 1, the lower ends of which are secured in a circular cast iron plate 2, and the upper ends of which are secured in a similar plate 3. The pipes are connected with the plates by taper metal joints, and the holes through the upper plate are of sufficient size to enable the pipes to be passed through them. This construction enables any defective pipe to be readily removed through the upper plate, and a new pipe substituted therefor. The outlet chamber is formed within the vcast iron base or outlet section 4 which is provided with a discharge outlet 5. The base sect-ion is provided with a horizontal flange 6 surrounding the outletvchamber and the plate 2 of the pipe section is se- 30 cured to this flange by a series of bolts 7. The cast iron plate 2 thus forms the top The inlet chamber 8 is formed within a top or inlet section 9, andpis provided with a supply opening 10. Thesupply opening is surrounded. by a flange 11 to which a pipe 12 leading from the exhaust of an internal combustion engine may be secured. The

top sect-ion is provided with a flan-ge 1390 which is secured to the plate 3 of-the pipe section by bolts 14. The cast iron plate 3 thus forms the bottom wall'of the inlet chamber.

The casing section which surrounds the e pipe section is formed of plates of sheet metal 15 and'vis vprovided at its upper and lower ends with cast iron rings 16 to which the metal plates are riveted. These rings are provided with horizontal Avlangcs 17 which are secured to the ianges 6 and 13 of the lower and upper end sections by bolts 18. VVateris supplied to the chamber with-` in the casing 15 through a pipe connected 4 with an inlet 19 and passes out of said chamber through a pipe connected with an outlet 20. With this construction the sections of the heater may be conveniently manufactured and readily assembled. In

case any'xrepairs/ are necessary, the top sec placed With a new pipe without removing'- either the pipe or casing sections. If necessary the casmg section may be readily removed Withont disturbing the pipe section or its connection with the base section.

In order tol prevent the iniowing gases from impinging against the joints in the upper plate 3 of the pipe section, a baille plate 21 is placed within the inlet chamber over the plate 3, and is providedy with openings 22 registering with the ends of the pipes 1. These openings are of smaller diameter than the holes in the plateB so that the steam is directed away from the joints.

Owing to the high temperature of the gases entering the inlet chamber, the vtop section is liable to become heated to a materially higher degree than the pipe section which is in contact With the water. This is liable to cause unequal expansion of the parts, resulting in injury or such distortion of the parts as to produce leakage. T o avoid this, the top section is provided with a Water jacket ,23 which may communicate 'with circulating pipes through flanged openings 24 and 25.

lVhile it is preferred to employ the speciic construction and arrangement of the parts shown and described, it will be understood that this construction and arrangement is not essential except so 'far as it is set forth in the claims, and may be varied without de arting from the invention.

aving explained the nature and ob'ectof the invention, and specifically descr d one construction of heater in which it may Vend plate of the pipe section is secured, and

a casing section provided with end flan es secured to the anges of the inlet and out et sections outside the end plates of the pipe section, substantially as described.
